WIND-WHEEL.

SPECIFICATION forming part of Letters Patent No. 489,885, dated January10, 1893.

Application filed July 8, 1892 Serial No. 439,328- (No model.)

To all whom it may concern.-

Be it known that I, MALCOLM B. WILLIAMs, a citizen of the United States,residing at Kalamazoo, county of Kalamazoo, State of Michigan, haveinvented a new and useful WVind- WVheel, of which the following is aspecification.

This invention relates to that class of wind wheels consisting ofsections composed of radial sails attached together by rims runningtransversely to said sails.

The main objects of the invention consist in the manner of fastening thesails to the rims and in the attachment of the arms to the sections, allof which is below described and is designed to make a simple, strongwheel and to especially facilitate the construction, by the mode offastening the parts.

In the drawings formingapart of this specification, Figure 1 is anelevation of a portion of the wheel, showing one section and part ofanother; Fig. 2 broken details from Fig. 1, in enlarged perspective;Fig. 3 abroken portion of the rim in Fig. 1, in perspective, enlarged;Fig. i a plan of a broken portion of the rim, enlarged, showing the modeof construction Fig. 5 shows an enlarged view of the rims in Fig. 1, inperspective, at the ends where they are attached; and Fig. 6 shows theseparts in Fig. 1, detached.

Referring to the lettered parts of the drawing, A are the radial sailsof the Wheel, made in the ordinary manner. The rims which hold the sailstogether are shown at B, said rims being preferably made of metal whichis channeled, or turned atthe edges, as shown in the drawing, for thepurpose of stiffening it and being enabled to use lighter material. Thesails are passed through slots, 0, in the rims, B, which slots areformed by cutting through the metal at the proper places, in a manner toleave portions of the metal to be turned up out of said slots, saidportions being shown at e. In Fig. 1 the rim is shown with the slots asI prefer to cut them, leaving the points e (which in said Fig. 4 havenot yet been turned up, but are shown turned upward in Fig. 3) ready toreceive the sails through the slots.

It will be observed that the main portion of the slots, 0, is made widerthan the space for the sails between the points 6, after the latter havebeen turned up. By this meansl secure longer points 6, to bear againstthe surface of the sails, A, than would be the case if the slots wereout only as wide as the thickness of the sails, and at the same timeleave a space between the side boundaries of the main slot and the sailas shown at o, in Fig. 2. To accomplish this, the lower bend in thepoints is a little inside of the boundary line of the main slot, 0,which will be seen at z, in Fig. 3. As many of these bearing points maybe provided as deemed necessary, two being here shown on one side of theslot and one on theother.

After the sails, A, are inserted through the slots in the rims, B, thebearing points, 6, are upset against the sides of the sails, as in Figs.1 and 2, which thoroughly attaches the parts together. A portion of theedge of the outer rim, B, in Fig. 1, is broken away, so as to show thepoint at 6.

While the slots, 0, are cut so as to show the points e, they may be cutso that the turned up portion of the metal which is upset against thesails A, may be otherwise shaped, although the points are deemedpreferable.

So far as forming the metal rims with the turned edges to stiffen themis concerned, the slots for receiving the sails may be otherwise formed,or said sails may be attached to them in any other desirable manner.

The ends of the rims, B,.where the sections come together, are lappedone on the other, as shown in Fig. 5. These lapping ends are gashed soas to form slots, S, from which slots the metal is turned up, formingtongues, E, integral with the ends of the rims, as in Fig. 6. WVhen theends of these rims, B, are lapped together, one of the tongues E, ispassed through the slot S, as shown in Fig. 5. The arms, D, are placedbetween these projecting tongues of the outer rims of the sections andpassed through the slots, S, and between the projecting tongues of theinner rims of the sections; and bolts are passed through said tonguesand arm. At F the lapping ends of the rims are riveted together. Thisprovides a very satisfactory attachmentof the rims and arms, it beingsimple, strong and easily made.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is 1. In a wind wheel, thecombination of metal 3. In a wind wheel, sections having metal rims withlapping ends where the sections are attached together, said lapping endsbeing provided with the slots and outwardly turned tongues, the tongueof one end turning outwardly through the slot of the other end, in

combination witharms bolted between said tongues; substantially as setforth.

In testimony to the foregoing I have hereunto subscribed my name in thepresence of two witnesses.

MALCOLM H. WILLIAMS.
